AU'roMoBILE JACK AND RIM Toon Application led September 16, 1925;Seria'No. 56H15'.V

rIhis inventiony relates to improvementsin automobile jacks; and rimtool, and more particularly' to af combinedVr toolwhich may be utilizedeither as a` jack or as a tool tov be used in spreading or contractingtire rims in making tire' changes or repairs.

The object ofthe invention is to provide a portable tool which may becarried as a part of the automobile equipment and servingto perform`either of the above mentionedfunctions withv thel advantage ofoomlai-ning` twotools in one;

The preferred embodiment of the inven tion is disclosed in theaccompanying drawings, in which Figurev 1E is a view in front' elevationof a tool'asrasseinbled` for use as a jack.

Figure 2 isa view' in side elevation of the tool as usedY as a= jack.

Figure Ll' isla. perspective view of the tooli showing its use as a rinrspreading device, an'dl .Figure 5 is zu` view inl elevationvshowing themanner of applying the tool to a tire rim.:

In common with lifting devices, the tool ofV the present disclosure whenused as a jack consists of ai pedestal 1 having a foot 2 at its lowerendV adapted to rest upon the ground and a step 8 at its upper:l enddesigned tio/engage under the axle: or other part of 'the vehicle to belifted. The pedestali 1 consists. of two extensibleA members #1 4identical in construction and eaclr con` sist-ing of a relativelystationary channel member inwliielr a bar 6 slides or telescopes. 1fdesired, these members which are shown as channel members may be tubularlllnou; hout a portion of their entire length, as shown at 7 7.

The extensible bars 6 6 project upwardlj7 beyond the ends of the channelmembers 5 5 and are provided along one edge with rack teeth 8. At theupper ends of the channel bars 5 5 is the rack bar elevating mechanismconsisting of a shaft 9 eX- tending transversely of the face of the rackteeth and journaled in pairs of flanges 10 1O projecting laterally fromthe upper ends of the. channel members 5 5. Keyed to the shaft 9 betweenthe pairs of flanges 10-10 are pinions 11 11 meshing with the rack teeth8 of the bars 6 6. Fixed to the outer face of one of the channel members(to the right as shown in Figure 1) is a verticall plate 12 providednea-n1 its lower end with a. shaft bearing 12a for the adjacent end ofthe shaft 9, to which is fixed a worm- Wheel 13. Integral,withthe upperportion ofthe plate 12' is an inverted lil-shaped yoke 111k in which isjournail'ed a worm 15 meshing with the worm 'wheel` 13. Connected withthe shaft 115 of the worm-15 is an operating handler 1 6 having auniversal or swivel@ joint connection 17, insertable in a tongue andigroove socket in the end of the worm Theupp'er ends of the rack bars 6 6are provided with laterally extending flanges 18' 18, which over-lapeach otherl and nest together so that the two rackl barsy present asolid end construction. Formed in the corresponding edges of' eachflangey 18 is a notch 18a, said notchesiV registering' with each otherwhen the barsf arey brought together side by side; Fitting'overtheflanged upper ends of the bars is the step 3 provided withy aV socket 3linto which the upper ends of the bars are inserted.

At the lower ends ofthe channell bars 5 5', asimilar arrangement? islfound wherein a flanged block 19 19', as clearly shown in Figure 4, islittediinto:A the end of' each channel' memberf, said-blocks havinglaterazlly` extending and.y iirterfitti-ngI faces so that when the twochannel bars are side by side the two blocks fit together to form: a

ysolid rectangular base which fits.` into an upstanding socket portion2r of the foot 2. As before', not-chesl 19 19EL are formedinA the side:edgesV of the' blocksv 119 19, these notches: not only being located. inthesame relative positions in the same vside edges of the blocks butcorresponding in position to the notches 19?* 181l at the upper ends ofthe rack bars 6 6.

When the tool is used as aj ack, the channel members 5 5 and the rackbars 1f-1 occupy vertical positions, side by side, as clearly shown inFigure 1, the upper and lower ends thereof being fitted into the foot 2and step 3, respectively. Thus by inserting the jack in upright positionunderneath the vehicle and rotating the handle 16, the rack bars 6 6 areelevated or lextended upwardly in the channel members by the powertransmitted through the worm 15 and worm wheel 13, to the shaft 9 andthence to the rack bars through the pinions 11, the telescopic movementof the bars within the relatively fixed. channel members 5 serving toraise or lowerV the vehicle in the usual manner. Y

Figures it and 5 show the tool as used for spreading a metal rimQO-ivhichv carries 'the' vehicle tire. vBy removing the foot 2 and.

step 3, the pair of telescoping rack and channel bars'may be swung-aboutthe axis of the.

may engage the laterally projecting fiange 20 which surrounds theperiphery of the rim. Assuming then that it is desired to contract thering so as to remove the tire, the tool is applied and by rotating thehandle 16 in a direction to shorten the arms, the pressure is applied sothat the rim is sprung at its joint and thus contracted so that it maybe demounted from the tire. Likewise, when the tire and rim are to beassembled, the tool is appliedvand the rim contracted to permit the tireto be placed on the rim and then by manipulating the tool, the rim isexpanded so that the proper connection can be made at the rim joint.

Manifestly the construction herein disclosed may be variously modifiedWithout departing from the spirit of the invention, and therefore I donot Wish to be limited except in so far as specified in the appendedclaims.

I claim as my invention:

1. In a tool of the character described, the combination of a pair ofrelatively iixed supporting members, an endWise extensible memberlocated in one of said relatively fixed supporting members, means forpivotally connecting saidrelatively fixed members to swing about acommon axis and in parallel planes, means for extending said extensiblemember. rim engaging members at the ends of wsaid supporting members andsaid extensible member, and a detachable foot member adapted to beapplied over the free ends of said supporting members.

V2. In a tool of the-character described, the combination of a pair ofendWise extensible members, ine'ans for pivotally connecting saidmembers intermediate their ends for relative'swinging movement about acommon axis and in parallel planes, said members having rim engagingextremities, and a detachable foot and step member providedwith socketsadapted to receive the opposite extremities o'f said extensible members.c

3. In a tool of the character described, the combination of a pair ofrelatively ixed supporting members, pivotally connected adjacent yoneend, extensible members located in said supporting members, and meansfor extending said pair of supporting and exten sible members, anddetachable foot and step members adapted to be applied at opposite endsof saidmembers.

4;. In a tool of the character described, the combination of' a pair ofendwise extensible members, means for pivotally connecting said membersintermediate their ends for relative swinging movement about a commonaxis and in parallel planes, and ,a detachable foot and step memberprovided With sockets adapted to receive the opposite extremities ofsaidv extensible members.

5. In a tool of the character described, the combination of a pair ofextensible members, pivotally connected together for relatively swingingmovement about a common axis, a separate rack and pinion acting througha single shaft, to extend said members simultaneously, rim engagingmembers at the opposite. ends ofsaid extensible-members, and detachablefoot and step members for said extensible members when in parallelposition.
